I fail to picture a scene where the pilot goes straight for a slump forward knocking the plane into a nosedive the second after he gets a heart attack with the copilot completely taken off guard with exactly zero seconds to realize what's going on and act appropriately. Except with simpsons graphics He starts to feel really bad, chess pain choking, then eventually starts to fall forward, ok. In the meantime the copilot has is right next to him and has enough time to react accordingly.
